my present invention to provide meansenabling the numerous users of my waxers to charge the same, in a cleanly, expeditious and economical manner, by the bodily insertion of novel wax cartridges in wax chambers especially adapted to receive thesame; and mypresent invention may accordingly be regarded as comprising not only an improved waxerand polisher but also novel-wax cartridges adapted to interfit therein and to cooperate with parts thereof, as hereinafter described.

Other objects of my invention, including the provisionof special wax containers or chambers adapted to be disposed at the lower ends of handles and preferably'each' having a smooth interior and/or an interiorly threaded cap, said invention including also the use ofa plunger havingv a smooth exterior, and means for so connecting the'same with a handle that the rotation of said handle advances said plunger, may-be best appreciated from the following descriptions of alternative embodimentsof my present invention, taken in connection with the appended claims and the accompanying drawings, in which Fig. 1 may be regarded as, for the most part, a substantially central vertical section through a wax organization illustrating one form of'my present invention, -this view beingtaken substantially in the plane of the line 1-1 of Fig. 2 (which, however, shows an alternative form of wax cartridge).

Fig.2 is a detail view,taken substantially as indicated by the line 22 of'Fig. 1, but

showing, as indicated, an alternative form of Fig. 3 is a view corresponding to .a. portion ofFig. 2-, but suggesting the use of a wax cartridge in the form of a collapsible-tube.

-Fig. 4 is an elevational View comparable with the upper portion of Fig. 1, but sh'ow- .ing an alternative embodiment of my invention in which, both during ordinary'manipulation (for a waxing or polishing effect) and during the expressing of wax (by the rotation of a handle) a threaded cap, provided above a wax cliambermay remain stationary, relatively to said. chamber.

Fig. 5 is a view comparable with Fig.4

but showing an alternative form of plunger,designed for use in the stripping .71;

of "wax from wax cartridges in the form of collapsible tubes.

Fig. 6 is a perspective view showing'the upper or closed'end of one advantageous form of a collapsible tube wax cartridge, comprising parts sodesigned or disposed as to facilitate a holding of same during a stripping of wax therefrom, as by means of a plunger of the general type illustrated'in F ig, 7 is a longitudinal or a vertical sectional view through one advantageous type of cartridge comprising a thin but substantially rigid shell. 2

Figs. 8 and 9 are respectively longitudinal or vertical sections, and j Fig. 10 is an elevational view, of further alternative forms hereinafter described.

Referring to the details of that specific embodiment of my invention shown in Fig. 1, 11?) being the main body of a waxer-or polisher of thegeneral type illustrated in my mentioned pending applications, 12?; is acylindrical wax container pivoted thereto and disposed coaxially with a main operating handle 13o, suitable for use in the application of wax and /or the polishing of floors, or the like, by means comprising the main head or body 11?), duly protected.

In this form of my invention, instead of providingthreads directly upon a handle 13?) or upon a thimble or plunger 14b, integrally or rigidly connected therewith, in order to adapt thesaid thimble or plunger to fit and advance within a wax cartridgecomprising a T0 renames rnonuc'rs cylindrical shell 15?), I avoid providing any threads directly upon the thimble or plunger 14?), preferably providing external threads at 16b, near the upper end of the wax container 12?), and providing internal threads, as at 176 upon a cap member 17 Z integrally or otherwise rigidly connected with the plunger or thimble l lln as by means of a screw or pin extending therethrough.

In order that an advance of the plunger or thimble 14b, as occasioned by relative rotation between the wax container 12?) and the cap 17?) shall be elfective to cause an advance or expression of wax from within a wax cartridge, of the general character referred to, and through, for example, a conical head 18?), shown as integral with an offset neck 1%, at the lower end of the wax container 12?) (said conical head being preferably integral with a threaded extension such as is shown at 20?), Fig. 2, adapted to carry a nut, or the like, and suitable washers for the retention of said conical head within a corresponding conical seat provided in an upstanding lug or projection 21?), as described in my last memtioned prior application, the ofiset neck 19b and the projection 21?) being respectively provided with means such as cooperating ducts 23?) and 24b for the conduction of wax toward the lower surface of the main body 11?), it is important that the thimble or plunger 14?), or its equivalent, shall fit somewhat exactly, whether or not it is rotated within the cartridge shell 156, or its equivalent; but said shell may fit somewhat loosely and be freely movable within the wax container 12b; and,

in order to facilitate the insertion, retention and replacement of a wax cartridge of the general character shown in Figs. 1 and/or 7, and in'order reliably to guide the thimble or plunger 146, or its equivalent thereto, the upper or entrance end of the cartridge shell 15?), may advantageously be outwardly flared, somewhat as suggested at 25?), so as to overlie a terminal shoulder 26?) at the upper end of the container 12?).

In order to assure a substantially circular cross sectional outline and a uniform thickness of wall, I suggestthe formation of the mentioned cartridges from extruded, or drawn or other tubular stock, rather than from a sheet material; and, although the respective ends thereof may be closed in any preferred manner, I suggest in Fig. 7, the use of a cap 276 at the lower end of a cartridge 28?) and the use of a cupped or other plug 296 at the opposite or upper end thereof. The diameter of the cap 27 b, when employed, may be such as to prevent the insertion of the cartridge within the chamber 12?), or its equivalent, until the said cap is removed; and th e cupped plug 29?), or its equivalent, may be adapted to form a wedging fit with the mentioned flared terminal portion 26b, at the upper end of the shell 15b,-one or both of the mentioned closure elements incidentally providing circumferential channels 307), suitable for the retention of any preferred sealing compound or material.

In Fig. 2 I suggest the use of an alternative type of cartridge 286, the upper end thereof being, for example, similar to that of the described cartridge 28?), but the lower end there.- of being shown as closed by a transverse element 316, permanently secured to a thin shell 15c and provided with an eccentrically disposed threaded nipple 32c,a correspondingly threaded cap (not shown) having been removed before the mentioned nipple is inserted in the manner illustrated.

Although a user might obviously use a cartridge in the form of an ordinary collapsible tube, permitting the wax delivered therefrom upon compression by a plunger 1%, 146, or its equivalent, to exit either through a lateral opening into an offset neck, as shown at 23?), Fig. 2, or through a centrally positioned opening, as suggested at 23d, Fig. 5, it will be obvious that the removal of the shell of a longitudinally crushed car tridge from a deep wax chamber may present a disagreeable problem; and I accordingly illustrate in Figs. 4 and 5 alternative constructions which, although they may be employed in connection with cartridges of the general character already described, are particularly suitable to use in connection with the expression of wax from so-called collapsible tubes. In Fig. 4 I show a cylindrical wax container 126 as provided with a cap 176 which, although interiorly threaded at 166 for engagement by a correspondingly threaded member which may be integrally or otherwise rigidly connected with a main handle for the manipulation of a polisher, is

provided with quick-detachable. means, in volving no use of a thread, for its connection to and disconnection from said wax container,-the mentioned cap and container being respectively provided with cooperating shoulders 266 and 336, adapted to cooperate in the retention of a flared portion 256 of a wax cart-ridge shell.

For the purpose referred to, I may provide the container 126 with a plurality of projecting lugs 34:6, interfitting within circumferential portions 356 of slots 366, in the manner of so-called bayonet connections; and, in order that the rotation of the handle or other threaded member 136, shown as carrying at its lower end a plunger 146, for the purpose of expressing the contained wax from the shell 156, shall be ineffective to disconnect the cap 176 from the container 126, I may provide, in connection with the described bayonet joint, or its equivalent, any desired latching or restraining means, such as, for example, a resilient dog 376. Although this form of my invention is suitable for use with cartridges comprising rigid shells, it is also suitable for use with cartridges in the form of removable tubes,the closed ends thereof being merely cut off, as with a knife or shears, and the metallic walls being so flared as to be engageab'le in the indicated manner be tween the described container and cap.

In Fig. 5 I show a form of my invention, comparable with that just described, but providing means for the use of a collapsible tube without cutting the same in such manner as to permit a plunger to pass therethrough. In this form of my invention, optionally using a chamber 12f of the general character illustrated in Fig. 4 and similarly connected with a removable cap 17 f I show a plunger 14 as substantially spherical in outline and as secured to the lower end of an operating handle 13f by a swivelled and play-permitting connection comprising a screw 38 shown as contained in the ball plunger 14; (optionally by the aid of a lock nut 39;") and as rotatable within a socket 40;, at the lower end of the mentioned handle 13f, said socket being formed in part by a removable section 41 shown as secured by a screw 42/. In the use of this form of my invention the upper end of a collapsible tube cartridge 12 may be retained between shoulders 26f and 33f in such manner that, upon the descent of the plunger 14f, or its equivalent, the contained wax is stripped from said tube, the upper end of said tube remaining conveniently accessible, for removal, upon the disconnection of the cap 17 from the container 12;".

Although collapsible tubes upwardly terminating in an ordinary manner may, especially if not initially filled quite full of wax, be secured and used in the general manner described, I prefer, after filling collapsible tubes with a suitable wax, to close the same in the general manner illustrated in Fig; 6,- the closing folds being given an arcuatc form, as at 437, in order to facilitate the insertion, retention and removal of the same in the general manner described.

In Fig. 8 I show an alternative in which a cap member 17 g is secured to a wax container 12g by a hinge 44g, a spring clip 459 being ser; cured, as by rivets 46g, to one of these mem bers and adapted releasably to engage a proj ection 47g on the other; the plunger 14g and shoulders 26g and 335/ being adapted to func tion and cooperate in the general manner above described.

In the form shown in F ig. 9, instead of using (as in the embodiments illustrated in F igs; 4 and 5) a comparatively shallow cap element associated with a deep container to receive the lower end of a wax cartridge, I associate a comparatively shallow container 12, 2, with a comparatively deep cap 171 2., in-

teriorly threaded to receive a correspondingly threaded handle 14h; and, instead of connecting the mentioned container and cap by.

ed to cooperate in receiving the threaded handle, terminating in 'a plunger head, incidentally to a recharging, the operative is enabled to restore the plunger'to its upper po sition without rotating the same.

Although I have herein described several alternative embodiments both of my cartridge retaining means and cartridges for use therewith, I believe I am the first to provide a waxer with any means whatever permitting the use of insertable wax cartridges; I'accordingly emphasize not only the fact that various features of my invention might be independently employed but also the fact that numerous modifications of my invention additional to those above described, might easily be devised by those skilled in the art to which this case relates, without involving the slightest departure from the spirit and scope of my invention, as the same is indicated abov and in the following claims.

I claim as my invention:

1. In means of the general character described; a waxer body having a wax delivery passage; a handle for manipulation of said body; a wax container mounted on the lower end of said handle and provided with an interiorly threaded cap adapted to cooperate therewith an apertured ear integrally formed on the top of the body and having a wax passage extending between the aperture in the ear and the wax delivery-passage; said ear and container being pivotally joined ;'the container. having an extension fitting into the aperture in the ear and arranged with a passageway communicating with the passageway I in the car; a plunger movable in the container and means whereby axial movement of the handle is effective to move said plunger.

2. In means of the general character described; a waxe-r body having a wax delivery passage; a handle for manipulation of said body; a wax container mounted on the lower end of said handle; a plunger movable in the container; said container being provided with an interiorly threaded cap adapted to cooperate therewith for giving lateral movement to said plunger, and through which said handle extends; an apertured ear integrally formed on the top of the body and having a wax passage extending between the aperture in the ear and the wax delivery passage; said ear and container being pivotally joined; the container having an extension fitting into the aperture in the ear and arranged with a pas- I sageway communicating with the passageway in the ear; and means whereby axial movement of the handle is effective to move said plunger. 3. In means of the general character dew scribed; a waxer body having a 'wax delivery passage; a handle for manipulation of said body; a wax container mount-ed on the lower end of said handle; said container comprises a part carrying a hinge; and a member so connected therewith as to provide access to the interior of said container; an apertured ear integrally formed on the top of the body and having a wax passage extending between the aperture in the ear and the wax delivery pas- 20 sage; said ear and container being pivotally joined; i he container having an extension fitting into the aperture in the ear and arranged with a passageway comn'iunicating with the passageway in the ear; a plunger movable in the container; and means whereby axial movement of the handle is effective to move said plunger.
